EaZ/pb MEN@ walls I5 comprised in the unit G. These walls I5 extend forwardly from the bar I at a distance substantially equal to the length of the plate 6 and are inwardly of the posts 1. The lower margins of the wall I5 are defined by the inwardly directed plates I6 of material width and which are freely and slidably received between the plates 6 and II.

The hinged portions of the side walls I5 are continued by the rearwardly and outwardly inclined wings I1 which provide a relatively wide entrance mouth for guiding a bundle or stack of folded articles or the like into the unit G. Each of the wings I1 has its lower marginal portionv outwardly and downwardly inclined to provide depending portions I8 to overlie and contact with the beveled corner edges at the forward end of the board B.

As is clearly shown in Figure 2, the top surface of the plate is substantially flush with the top surface of the board B so that a stack or bundle to be bagged will have unhampered passage from the board B upon the plate 6. It is also to be noted in Figure 2, that the plate or table 5 and the plate II are so spaced from the underlying surface of the table or base board 4, to permit readily the application of a bag 2I upon the unit G and the associated top unit T.

The top unit T, as herein embodied, comprises an elongated plate 22 of a length substantially equal to the length of the plate 6. The plate 22 is gradually reduced in width from its rear end to its forward end with the rear end of a width closely approaching the width between the upper portion of the posts 1 between which said end portion is arranged. The forward end of the plate 22 is continued by an elongated return extension plate 23 overlying the plate 22. This plate 23 is of material width of substantially the same width as through its length. The plate 23 terminates a predetermined distance inwardly of the rear end of the plate 22 and said rear extremity of the plate 23 is secured to the plate 22 by the rivets 24 with a supplement plate 23 in advance of such connection as at 24 being free of attachment to the plate 22.

The inner or connected end of the plate 23 is formed to provide a depending flange 25 arcuate in cross section from end to end and which hooks or engages over a supporting shaft 26 for the top unit T. The shaft 23 is of a length to bridge the space between the upper portions of the posts 1 and is provided with the reduced threaded extensions 21 at its ends which are disposed through the slots I2 of the posts 1. The ends of the shaft 26 surrounding the extensions 21 provide shoulders 28 for contact with the inner or opposed faces of the posts 1 at opposite sides of the slots I2 as the diameters of the rod 26 at the ends are greater than the widths of the slots I2.

Threading on the extensions 21 outwardly of the posts 1 are the clamping or holding nuts 29 for contact from without with the posts 1 whereby the top unit T may be maintained a desired selective height with respect to the unit G within the limitations of the slots I2.

The top unit T also includes the side walls 33 of lengths substantially the same as the length of the plate 22 and the forward free marginal portions of the walls are rounded or otherwise reduced to assure desired effective cooperation between the units G and T.

The upper margins of the side walls 30 are defined by the inwardly directed flanges 3| which are of considerable width and which are freely 4 received between the plates 22 and 23 whereby the side walls 36 have free lateral movement with respect to the plate 22.

The rear portions of the flanges 3I at the outer corner portions thereof having fixed thereon from above the bearing member 32 through the shaft 26 is loosely disposed. The looseness afforded by the bearing member 32 is such to allow for the desired lateral swing movement of the side walls 30.

The supplemental plate 23' is riveted as at 33, to the upwardly and outwardly curved portion 34 at the rear of the plate 22.

In practice, the shaft 26 of the top unit T is raised up along the post 1 to a selected position as determined by the size of the bag 2l or kindred container to receive the insert. After such adjustment, the nuts 29 are properly turned to effect a clamping of the shaft 26 in such position. Before an insert is applied, the top unit T will be disposed outwardly and downwardly, as shown in Figure 2, with the outer portions of the walls 30 in contact with the outer portion of the plate E. The required adjustment of the top unit T as hereinbefore mentioned is preferably obtained by placing the insert upon the plate 6, and then lowering the top unit T until the plate or panel 22 is in reasonably close or snug contact with the top of the insert.

The bag 2I is applied over the outer ends of the units G and T while the unit T is in a position as shown in Figure 2 with the bag extended a material distance inwardly of said members G and T.

After the bagv 2I or the like has been applied. the insert is placed on the board B and then pushed outwardly between the units G and T (Figure 3), the operator holding the bag in place as by the string b or otherwise as may be preferred.

It is to be explained that the smaller the diameter of the bag 2I or the like, the less distance it is to be pulled on to the units G and T.

As the insert moves outwardly, it lifts the top unit T (Figure 3) so that the bag 2l is effectively gripped when the insert reaches the bottom of the bag.

The loader as herein embodied may be used with equal facility with bags of varying sizes within certain limitations as determined by the size of the insert. It is only required that the operator adjust the angle of the top unit T by adjusting the shaft 2B along the slots I2 as required.

When going from a small size insert to a larger, the insert as it enters between the units G and T by outward pressure on the walls I5 and 3U, will automatically adjust the members G and T laterally.

The board or ramp B is provided with the beveled margins. 35 to facilitate the moving of the insert from the base board or table 4 upon the board B so that the insert will be on substantially the same level as the upper surface of the plate 6 of the unit G.

The plate 6 is also preferably held to the board B by any preferred means but preferably by a. screw and this screw may be passed through the flange 8 into the adjacent end of the board or other location as desired.

It is to be pointed out that the inwardly directed flanges I6 are tapered from the rear outside edge toward the forward inside edge so that such fianges will not contact the flange 8 of the plate '6 when the unit G is in its fully closed adjustment. The inwardly directed flanges I6 are also tapered from the rear inside edge toward the forward outside edge so that there' will not be any overlap when the unit G is closed fully and thus assure free working between plates 6 and Il.

The inwardly directed anges 3l are tapered from the rear inside edge toward the forward outside edge so that such flanges will not overlap when the unit T is fully closed and to permit the same to work freely between the plates 22 and 23.

In the embodiment of the invention as illustrated in Figures 11 and 12, each of the members M of the body unit is not hingedly connected to the associated post but in this embodiment there is interposed between the side wall I5 of the member M and the upright or post 1' an elongated wedge member W and this member W, together with the adjacent side plate I5' is held to the upright or post 1' by the bolts 36 which are herein diseolosed as inserted through such elements from within and have associated therewith the conventional holding nuts 31. It is to be noted that the high portion of the wedge member W is disposed toward the forward end of the member M to assure the side wall I5' to be normally disposed inwardly at the limit of such movement of the member M. It is to be stated, however, that the inherent resiliency of the material from which the member M is produced will allow the top and bottom units to open up to maximum when loading large size bags.

From the foregoing description it is thought to be obvious that a bag loading or filling device constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.
